reference being'had to'the'accompanyng drawing forming part of this specification, irr which- ..Figurel is a side viewiofmynnproved maehinc Figure 'is 'a top View of the s'a'n'1e,'parts being broken away to show the construction. l i

Figure 3 is a detail vertical longitudinal section of 1-My invention `has for its object to `furnish a` simple,

seed from blue-grass, whilestaiiding inthe iield; and It consists 'in theconstruction and combination of the various parts of the machine, as hereinafter more fuily described. 3 i i A are the drive-wheels, which are connected with and revolve upouthe axles lof the axle-tree B in the ordinary` manner; y y

C are the thills, the rear parts of which are secured to the axle-tree B, andthe rear endsof which are connected by a cross-bar, cl, tha t supports the driver-s seat D. The tbills C, a little in front of the forward edge of the machine, are connected by a cross-bar, 0, to

` which thewhifetree is pivoted.

E is the boxor body of the machine, which is hung from bearings 'orjournals formed upon the axle-treel by means of brackets or bearings attached to the said ibody or box E, said brackets having second holes ,i Fare the stripping-teeth, the rear ends or bases of which are securely bolted to abeam, which is securely, but detachably, bolted to the forward edge ofthe body or box E, so that it maybe conveniently detached from the machine when required, for convenience in lrepairing the teeth F.

The teeth F are `concaved upon their upper sides, and are so formed as to leave narrow spaces or openings between theadjacent side edges ofsaid teeth,

y which allow the fine stalks of the blue-grass to pass y,throng-h, but willstripoif the seed.

T01 give the teeth F sufficient strength to strip off ,the seed, the said teeth are strengthened by a flange `or rib, f formed upon orattached to their lower sides, as shownn g. 3.

v :The grass is forced Aagainst the teeth F, as the machine is drawn forward, by the reel G, which is made p p i whenkth'e machine is movel backward. convenient, and effective Vmachine Ifor stripping the I 4 side boards of the box or body E, and upon it, just The Scfxedulerefevrre'd'toin theseLetter Patent making part of the same somewhat similar to Athe reel of a harvester, and the journals of whehrevolvc inbcarings attached tol the4 forward ends of the sideboards ofthe body or'box Ef.-

lhe reel G is revolved, as the machine is drawnfor-f'f v ward, by the bandll, whichpasses around the pulleyl I attached to the. projeetingend ofthe reelfshaft, and

around the pulley J attached 'to one4 of the dr' wheels A. I With ther-other drive-wheel 5A is rigidly* connected aigear-wheel, .K,.intorthc teeth of which mesh the teeth of the gearwl1eel L,whichrnns'looselyl upon the projecting endl of the-crankshaft M, and

i which connected with said crank-shaft M` by a spring.

.pawl and ratchet-heel in such a` wayas to carry the said 'crank-shaft with, it when the machine. is drawn forward, andto allow, thcfs'aid crankshaft to'standstill --lhe` `shaft M ,revolves in bearings attached lthev inside of the said side boards are formed two cranks m', to which are pivoted the rear ends of the connect- To the forward side of the bar O is attached a metallic plate or knife, l), which is drawn back along the upper surfaces of the teeth F, to Lh'aw the seed back into the body or box E, as it is stripped from the blue grass bythe said teeth To the forward side of the plate P is attached a rubber plate, Ob, for the purpose of cleaning off the said teeth F.

In the connecting-bars N, near their forward ends, are formed curved slots a', through which pass'pins It, provided with friction-1"ollers,` and securely attached to the side boards of thebox or body E, to serve as pivots or fulcrums for the said bars N, so that, as the rear ends ofthe bars N are carried downward and forward by the action of thecranks in', the forwardends of the said bars and the attached scraper and rubber may be carried upward and forward, to pass over the seed upon the teeth F.

lAs the rear ends of the bars N are carried upward and backward by the cranks m', the scraper P and ing the seed back into the box or body E.

The scraper P and rubber Q are made to move in` i -a slightly diagonal direction, as they are drawn back, by the inclined blocks F attached to the inner sides ofthe forward parts of the side boards ofthe body or bex E, and against which the ends of the bar O rest.

,S is' a bar or plate connected with the middle parts ofthe bars N by springs T, which hold the said plate S down upon thebottom of the box or body E. so as to take the seed where it is left by the scraper P and draw it further back inte-the body or box E.

U is a guard-bar, the ends of which work in bearings in the forward parts of the side boards of the body E, and which is bent -twiec at right angles near its ends, to pass over the reel G, so that it may be turned down against the peints of the teeth F, to prevent the said teeth from operating when the machine is passing through patches of weeds, clover, or other vegetation that would foul the seed or clog the machine.

gear-wheel, V, into the teeth of whichmesh the teeth of the segmental gear-wheel \V, formed upon or attached to the end of the lever X, which is pivoted to the side boards of the body or box E, and the other end of which entends up into such a position that it may be reached and operated by the driver from his seat.

Y is a catch, secured in such a position that it may catch upon and hold the said lever lwhen moved downward to hold the guardbar U against the ends of the teeth F.

Z is a spring attached to the body or b0x` E, and the free end of which rests against the under side of the rearpart of the lever X, so that, when the said lever is released from the catch Y, the said spring may operate the said lever to raise the said guard-bar U away from the teeth F.

A are two connecting-bars, placed one upon each side ofthe machine, and the lower ends of which are pivoted to the forward parts of the said boards of thc box or body E, and the upper ends of which are pivoted to the forward 'ends of the arms B', the rear ends of' which are rigidly attached to the ends of the shaft G', which works in bearings attached to the thills C.

lo one end of the guard-bar U is attached a small of the grass to be stripped, without interfering with the proper operation of the vamous parts of the machine.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent c 1. A connecting crank-bar N, having the curved slot n', combined' with a fixed guide-pin R, to carry the scraper and cleaner over the'seed in its forward movement, as set forth.

2. The combination ofconeave strippers F, scraper P, connecting-bars N, and spring plate S T, by whose co-operating instrumentality the seed is stripped and delivered.to the receiving-box.

3.- 'lhe vibrating guard-bar U, pivoted as described, bent at right angles t0 its length on each eno, and brought in front of the teeth, to prevent them A`from stripping weeds and other grasses of their seeds. v

4. The combination of rack and pinion V W, catch Y, guard U, fingers F, and body E, all constructed and relatively arranged as and for the purpose specitied.
